Specification of Letters Patent.

Patented Dec. 12, 1905.

Application filed December 12, 1904., Serial No. 236,451.

T0 all whom, it may concern:

Be it known that I, BARTLETT ARKELL, a citizenof the United States, and a resident of New York city, in the county and State of NewYork, have invented certain new and useful Improvements in Bags, of which the following is a specification.

This invention relates to improvements in compound bags, such as consist of an outer bag of suitable material and an inner bag of paper.

The invention seeks, primarily, to form the bottom of the inner bag in such a way that it shall be capable of yielding at the bottom when put under strain due to the inclosed material. l

The invention further seeks to do away with forming the inner bag of a compound bag with a closure at the bottom consisting solely of means such as a line of stitching or glue, so that when the bag was filled there was no way of protecting this closure at the bottom of the bag from the great strain put upon it by the inclosed material. In such cases the inclosed material bore directly upon the line of closure at the bottom of the inner bag, thereby tending to tear or break the bag at its line 0f closure. As the filled bag frequently rests upon its bottom and is frequently dropped forcibly upon its bottom, the strain upon the bottom of the inner bag at its line of closure is sometimes very great. According to the present invention the line of closure at the bottom of the inner bagis protected in a very simple and eicient manner. The invention contemplates also in the same way the protec-L tion of the side closure of the inner bag, although the side closure is not generally under such great strain as the bottom, and hence it is not so important to protect it.

In my prior patent, No. 565,587, granted to me on the 11th day of August, 1896, I de` scribed a compound bag of which the inner bag is made of stretchable paper. The stretchability of the inner bag described in my prior patent secures an important advantage; but the bottom and side closures of the bag were not protected from the great strain put upon them. In other words, the inner bag could yield over its entire area except at its bottom and side closures; According to the present invention I am able to so construct the inner paper bag that it will also yield at its bottom and side closures.

The invention also seeks to protect the inner bag from damage due to handling. This is done by forming ears at the lower corners of the outer bag and turning up the corresponding corners of the inner bag.

In the accompanying drawings, forming part-of the specification, and in which like reference-numerals designate corresponding parts, Figure l is a reduced side elevation of a bag made in accordance with the present invention and showing part of the outer bag cut away. Fig. 2 is a sectional perspective view of a lower portion of the inner paper bag and before the bottom has been turned up to form a free fold. Fig. Sis a similar view to Fig. 2, but showing the bottom turned up to form a free fold. Fig. 4 is a side view of a lower portion of the inner bag, showing the free fold and having one corner turned up. Fig.' 5 is a sectional elevation of the lower portion of the compound bag after the same has been filled, the sectional line being across the bottom closure. Fig. 6 is a reduced perspective view of an inner bag having free folds at its bottom and two side closures.

Referring now specifically to the features as the same are particularly shown in the drawings, l is the outer bag, which is preferably made of burlap or other textile material. 2 is theI inner bag, made of paper and preferably made of stretchable paper having crinkles or a multiplicity of tight creases, such as that shown in my prior patent above referred to. 3 and 4: are ther two pieces constituting the body of the bag, the bottom of which is turned up to form a fold 5, which is secured to the body of the bag by the line of stitching 6. This line of stitching 6 constitutes the closure at the bottom of the bag. After this closure is formed the bottom is then turned over to form a free fold 7 The crease or line 8 of this fold is generally pressed down firmly, so as to keep the fold in place. fold is formed in the paper bag it is then inserted within the outer bag l. The contained material 9 enters between the sides 3 and lof the inner bag, so that the material of the inner bag disposes itself as shown in Fig. 5. It will be seen that the weight of the contained bottom of the outer bag. It will also be seen n that the stress of the contained material After the free IOO ,operates to hold it in place flat against the against the sides of the inner bagis not communicated to the line of closure of the inner bag-that is, to theV line ot' stitching but is received by the free fold 7. Thus the free fold protects this line of closure -from the strain which would otherwise be put upon it and would probably result in tearing the par' per at the line of closure. The strain of the contained material tends to pull out the free fold; but this strain cannot reach the line of closure-that is, the line ot' stitching-until the free fold is entirely pulled out. The weight of the contained material directly upon the free fold of course tends to maintain the free fold in place and prevent it from pulling out. As a result of this arrangement the bottom of the inner bag is able to stretch or yield in the region of its line of closure instead of being unyielding, as heretofore made. Thus the inner bag is prevented from tearing out at its line of closure.

In order to prevent the inner bag from being torn when the filled compound bag is handled, the lower corners of the outer bag are provided with ears 10 and 11. These ears may be formed by the diagonal rows ofstitching 1Q- and 13. The inner bag has its lower corners turned up, as shown at 14, so that when the outer bag is grasped by its ears the corners of the inner bag will be out of the way and the inner bag thus saved from dam- .age

If desired, the free fold 7 may be formed also at one or both side closures of the inner bag. (See Fig. 6.)

It is obvious that unless the bottom closure of the inner bag is made stretchable it cannot yield to strains in the direction of this line ot' closure. To enable the inner bag to stretch or yield along this line, I mayform a free fold, one or more, across this line of closure. This arrangement has its advantages and is withinthe scope of my invention.

Although. I prefer to form the free fold oi the inner bag so that the line of closure is within the free fold, as shown in the drawings, it is to be understood that the Jfree fold, one or more, may be formed along and at one side of the line of closure without departing from the spirit or scope of the invention.

By the term line of closure as herein used Ido not mean to include merely a line of closure which has a seam,whether stitched, glued, or otherwise formed, but I also include within the term a line of fold such, for example, as when the inner bag is made of one piece of paper with a fold at the middle and closed at the side edges. In this case the fold at the middle would constitute the line of closure at the bottom of the bag'.

What I claim, and desire to secure by Letters Patent, is

1. A compound bag comprising an outer bag and an inner bag, the inner bag being made of paper and comprising two similar sides joined at the bottom `ot' each at their line of closure; and a free fold parallel to the line of closure and extending across the bottom of the inner bag to relieve straintransverse to the line of closure.

2. Acompound bagcomprisingan outer bag and an inner bag, the inner bag being made of paper and comprising two similar sides joined at the bottom of each by a stitched seam at the line oi' closure; and a free fold extending across the bottom of the inner bag parallel to said line of closure to relieve strain transverse to the line of closure.

3. Acompoundbagcomprisinganouter bag and an inner bag, the inner bag being made of paper and comprising two similar sides with their bottom margins folded together and secured by a line of stitching, said inner bag having said stitched fold turned up to form a free fold.

4. A com pound bag comprising an outer bag and an inner bag, the inner bag comprising two similar sides of vertically-crinkled paper With their bottom margins folded together and secured by a line of stitching, said inner bag having said stitched fold turned up to form a free fold.

5. Acompound bag comprising an outer bag of textile material and an inner bag of paper, the outer bag having, ears formed at its lower corners, and the inner bag having its corresponding corners turned up, whereby when the outer bag is grasped by said ears the corners of the inner bag will be out of the way and the inner bag thus saved from damage.

6. Acompound bag comprising an outer bag of textile material and an inner bag of paper, the outer bag having ears formed at its lower corners, said inner bag having its margin at the bottom turned up to form a free fold, and said inner bag having its lower corners turned up so as to be out of the way of said ears, substantially as set forth.

In testimony whereof I have signed my name to this specification in the presence of two sub.- scribing witnesses.
